The general object of my present invention is to provide an improvedcombination of a sn'ioking utensil, such as .a pipe, or cigarette orcigar holder with simple and eliectivc means, for eliminating orrendering innocuous injurious and objectionable constituents of thesmoke from tobacco or tobacco-like materials, as the smoke passes to Iobtain an effective filter action. Without creating an objectionableresistance to the flow of the smoke, and whereby more time than usual isgiven for chemical action of the filter on the smoke, and whereby Iprolong the useful life of each filter which terminates when the filterbecomesso fouled by retained impurities as to impair its filteringproperties, or to unduly obstruct the flow of smoke through it. Thefilter is especiallycharacterized by its flat pad-like form, whereby itsconstruction is rendered easy and its assembly in the holder simple.,Vith this form of filter, the smoke flow. path in the holder isrelatively large, and filter renewal may be quickly and easily effected,when fouling of the filter makes renewal deeirable.

In the combustion of tobacco, the gaseous and vapor constituents such asnicotine and others which are most deleterious to the smoker, arealkaline and basic in chemical character, and preferably, though notnecessarily, I incorporate in the filter, a suitable chemical foreliminating such deleterious substances or for rendering the latterinnocuous. The material used musthave acid properties and must bepractically suitable, in that it should be cheap and easy to procure andone which does not itself 'give'a harmful or objectionable odor or tasteto the smoke. Filter materials having acidfproperties which I have triedwith satisfactory results, include such acids as boric, salicylic andbenzoic acids, and the filter material rial no. 60,477)

which I now prefer is powdered boric acid. I have found that boric acidused in the manner described in addition to eliminating objectionablesmoke constituents, is advantageous because of its beneficial action onthe throat of the user. the manner described not only does not irrita cthe throat ofthe user, butexerts aheal ing effect when the throat hasbeen irritated or inflamed from some other cause.

In the preferred mode of construction of my improved filter I mayincorporate the chemical material with acid properties in a porousfilter body of fabric or paper, by coating or impregnatingthe body Witha solution containingsaichmaterial and then drying the filter in whichcase the acid crystalsformed when the filter dries arcinterspersedthrough the latterl When the Boric acid used in a filter is formed inthe manner described, I

advantageously line or cover it at one or both sides by a protectivelayer of thin porous cloth. At present, I prefer in practicelthat thechemical material with acid properties employed in the filter be in theform of a powder or mass of fine granules, and be held between-layers offabric. The fabric which I prefer to employ is a rather thick andloosely woven web of Wool, wool beingsomee what preferable to silk andmuch superior tocotton for the purpose although cotton, silkor linen canbe used. y a y 7 The various features ofpnovelty which characterize myinvention are pointed out with particularity in the claims annexed toand forming a partof this specification. For a better understanding ofthe invention,

however its advantages] and specific [objects attained with its use,reference should 'be had to the accompanying drawings and descriptivematter. in whichI have illustrated and described preferred embodimentsof the invention. I

Of the drawings Fig. l is a longitudinal section through a cigaretteholder: and

In the preferred form of my invention as shown in the -drawings, Arepresents a p cigarette holder of tubulardorm terminatin? at one end ina mouth-piece A and having an internally threaded socket secured to itsopposite end; to. receive a cigarette. lfhe barrel or body i if theholderis half cut away at its upper side for the major portion of itslength, the opening being closed by a part E semi-cylindrical in crosssection. The part E is secured to-the body part A at the end remote fromthe mouth piece A by the end piece B which is provided with aninternally threaded socket B receiving end portions of the body part Aand the end member E which unite to form an externally threadedcylinder. 'At its other end the part E extends under a cylindricalflangeA carried by the member A", and which advantageously is in theform of a metal band surrounding the holder. A filter C inthe form of afiat pad-like structure is clamped atits edges between portions of theparts A and E. To minimize the possibility of leaky joints, thelongitudinal edges of the part E are provided with oppositely inclinedsurfaces E which unlte With corresponding side edge surfaces A of themember A to provide diametrically opposed V-shaped channels opening intothe bore of the cigarette holder and in which the edges of the filter Gare received. To assist in bringing the side edges of the parts E and Ainto proper register and in sealing the joints. against air. leakage,the part A is advantageously provided with longitudinal rib portions A!at the outer edges of the surfaces A which enter rabbets formed for thepurpose inthe member E at the outer edges of the surfaces E The filter O's advantageously formed by two rectangular strips of woolen cloth orother-suitable porous fabricwith a layer D of powdered boric acid or thelike, between the fabric layers. There may be more than two layers ofcloth and more than one layer of the chemical, but ordinarily I considera single layer of chemical between two layers of cloth sufiicient. Thefilter C divides the chamber space in the cigarette holder into twocompartments a and a? A mouth piece channel A inclined to the end. ofthe mouth piece A opens into the compartment a, while the smoke drawnthrough a cigarette heldin the end piece 13 enters the compartment athrough a suitable port E formed in the endportion of the member E.

It willbe understood, of course, that the cloth portions of the filter Care of themselves effective to arrest dust and condensible tar oil andlike vapors in the smoke, and also to arrestsome of the nicotine andother positively deleterious constituents of the smoke. Along With asuitable material having acid properties, I may incorporate in thefilter other materials to perfume or flavor the smoke. e

In the assemblyfof the smoking utensil shown, the filter padC is placedin position in the barrelA and tile part E inserted under the flange Awiththe surfaces E uniting with the surfaces A of the member A to holdthe edge portions of the filter C in semi-cylindrical member.

Certain novel and patentable features dis closed but not claimed hereinare claimed in my prior application Serial No. 60,477,

filed October 5, 1925, of which this applica tion is a division.

lVhile in accordance with the provisions of the statutes I haveillustrated and described the best forms of my invent-ion now known tome, it will be apparent to those skilled in the art that the generalprinciples of my invention may be embodied in other forms ofconstruction, and I do not wish the claimshereinafter made. to belimited to particular details of construction and arrangement disclosedherein more than is made necessary by the terms of the claims and by theprior state of the art.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A smoking utensil comprising a tubularbarrel, a flat pad-like filter extending axially of said barrel anddividing the interior of said barrel into two compartments. 1 2. Asmoking utensil comprising a barrel having a chamber therein, a flatJud-like filter extending axially of and dividlngsaid chamber into twocompartments, an inlet passage at one end of one compartment and anoutlet passage at the opposite end ofthe other compartment.

3. A smoking utensil comprising a tubular barrel member having a mouthpiece at one end thereof and a cut away portion. at one side thereof, asemi-cylindrical member secured to. said barrel member along its cutaway. portion, and a filter pad extending axially of said barrel memberand secured in position between said barrel member and 4. A smokingutensil comprisinga barrel portion consisting of two semi-cylindricalparts, and a filter having its side edge portions gripped between saidsemi-cylimlrical parts. i a i 5.
